RNG and Biogas Events in Autumn 2025

A Personal Take on the State and Spirit of Renewable Gas in North America and Europe

Written by Ryan Hart, Renewable Energy Analyst at BiogasWorld

The autumn of 2025 offered a vibrant showcase of the renewable natural gas and biogas industry’s resilience, ingenuity, and forward drive. Attending several pivotal events this season has left me not just with new education and connections, but with a new confidence that the industry will navigate the challenges that emerged in 2025.

The premier fall American tradeshow, RNG WORKS, took place September 24-25 at Music City Center in Nashville, TN. The event, hosted by the RNG Coalition, featured two packed days of networking, education, and workshops: connecting professionals and showcasing the growth of the RNG sector across the United States. This marked my third attendance at RNG WORKS, and a noticeable shift from recent years Over the past year, a major industry transition ended the somewhat inflated confidence that the accelerated growth of the RNG industry, enjoyed over recent years, will continue indefinitely. For many, myself included, the market adjustments have created uncertainty for the future of the industry. My experience challenged that. While uncertainty was in the air during RNG WORKS, many people I spoke with had a cautious optimism that the adjustments are navigable, a speed bump. The narrative had shifted: the sector is not declining, but recalibrating for sustainable, long-term growth. RNG WORKS 2025 clearly demonstrated the industry’s remarkable ability to adapt quickly in the face of shifting markets. I left Nashville feeling more optimistic than I have been in some time about what 2026 will hold.

Back on Canadian soil, the Value of Biogas West event unfolded October 6-8 in Calgary, Alberta, hosted by the Canadian Biogas Association. The Western Canadian biogas and RNG sector was on full display, with 350 professionals gathering over three days to exchange ideas, forge new partnerships, and delve into the latest developments. Two site visits: GrowTEC’s Perry Farm and Calgary’s Bonnybrook Wastewater Treatment Plant, offered tangible evidence of innovation in action. I’ve attended many CBA events, and the passion and energy that fill the Canadian biogas market are unmatched. Further, Alberta’s recent passage of Bill 44, heralding new digestate management regulations, carried an unmistakable sense of excitement. The province is now positioned to lead on digestate utilization, replacing synthetic fertilizers and enhancing agricultural sustainability. Alberta’s vast pipeline network and agricultural sector are enabling impressive RNG connectivity and offtake possibilities. For me, these Canadian gatherings are a reminder that, despite the hurdles and delays, our community is tenacious. The people pushing this industry forward are tireless, and Alberta’s regulatory progress is a meaningful signpost for other provinces. I am convinced that, if we persist, biogas can become a cornerstone of sustainable energy, waste management, and emissions reduction across Canada.

Rounding out the season, Biomethane Week in Brussels (October 14-15), hosted by the European Biogas Association, brought together more than 1,000 industry leaders at the Autoworld museum. The focus was clear: biomethane’s role in supporting a strong, independent, and competitive Europe. The urgency was palpable, energy security and increasing resilience against supply chain shocks dominated conversations; the macro and micro benefits brought forth by decentralized sources of energy production. Achieving the EU’s ambitious target of 35 billion cubic meters by 2030 will require public support and robust communication about the local benefits of anaerobic digestion. In many ways, this mirrors the challenges and opportunities we face in North America: the need for broad stakeholder buy-in and the recognition that collaboration is required to move the industry forward and build support through all levels of our communities.

Looking back on these events, I can’t help but feel a renewed sense of purpose. 2025’s gatherings have reinforced my belief that, even as the road ahead becomes more complex, the spirit and resolve of the biogas and RNG industries are stronger than ever. Each forum I attended was evidence that, with the right regulatory support and a passionate community, real momentum is not just possible, it’s already underway. As I look toward 2026, I do so with optimism not just for growth, but for meaningful transformation.
